The Inquirer has an article on AMD's upcoming processor generations:
AMD IS NOT sitting on its hands in the face of the Intel Merom attack. It has the imminent Rev F cores coming, and after that, there is the somewhat mysterious K8L as it is mentioned, no doubt followed by others. If the current gen parts are Rev E, the next is Rev F, what is G and H, and when will they be out? E is 2005, F is 2006, so that would put G in 2007 and H in 2008.
We all know about F, code named Santa Rosa for the 2xx/8xx Opterons, and Santa Ana for the 1xx. They bring a new memory controller, DDR2-800, and all the long talked about goodies to the mix, and should be out at Computex. One thing it is not talking about on these beasties is enhanced memory RAS and quad-port crossbars.
